A few more Torx screws hold the lonely fan in place.

We were hoping to find a new asymmetrical fan, and we were not disappointed!

The wider gaps in the fan blades are around 3.6 mm, while the narrower ones are approximately 2.8 mm.

If you're not familiar with all the hype, the "asymmetrical" design of the fan blades is supposed to disperse sound across a wide range of frequencies, rather than just one, making fan noise "hardly perceivable."
